Comparing College Employment Rates

Competency C: Understand and Use Numbers
Task Group C4: Manage data
Level: 2
At this level, learners: Make low-level inferences to organize, make summary calculations, and represent data

Performance Descriptors
The learner:

• Calculates using numbers expressed as whole numbers, fractions, decimals, percentages, and integers
• Understands and uses ratio and proportion
• Makes estimates
• Finds ranges for data sets
• Calculates averages (mean) and percentages
• Identifies medians and modes
• Collects, organizes, and represents data using simple tables and graphs
• Interprets rates (e.g. crime rates) and ratios (e.g. shots–on-net to goals)
• Interprets, represents, and converts values using whole numbers, decimals, percentages, ratios, and simple, common fractions (e.g. ½, ¼)
• Chooses and performs required operation(s); may make inferences to identify required operation(s)
• Selects appropriate steps to solutions
• Recognizes patterns and begins to identify trends in data (e.g. population, crime, demographic, inventory, injury)
• Uses strategies to check accuracy (e.g. estimating, using a calculator, repeating a calculation, using the reverse operation)

Task Descriptors

• Scope of task is clearly defined
• May include unfamiliar elements (e.g. context, content)
• Requires the use of rates, or requires two or more operations, where operations are easily inferred
• Requires up to a few steps to complete
• May be completed in more than one way
• May involve one document (e.g. simple table, simple bar graph)
• May require calculating percentages
• May require converting between whole numbers, decimals, fractions, ratios, and percentages
